Router firmware for the TP-Link TD-W8901G, hardware version 3.4, marked OK in the name to indicate a working, verified image. It comes as a 1.06 MB RAR archive. A dump like this is typically written straight to the serial flash chip on the router board with a programmer such as a CH341A when the web recovery path no longer works. Match the revision on the device label first, since images for other revisions of the same model can differ, and always keep a read of the original chip before erasing it.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
